IMPROV EMENT IN SCHOOL-DESKS.

Specification forming part of Letters Patent No. 121,543, dated December5, 1871.

To all whom it may concern:

Be it known that I, IsAAo NEWTON PEIROE, of the city of Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented acertain Improvement in School-Desks, of which the following is aspecification:

My invention consists in a folding school-desk, having the several partsarranged and constructed as hereinafter described.

Figure 1 represents an end el vation of a section of the desk. Fig. 2isa partially side elevation. Fig. 3 is an end elevation when folded up. Ais the end frame of the desk, and may be made of cast-iron or any otherstrong material.

D is the desk-lid. S is the seat. B are the braces that are Iastened tothe desk-lid D, and move or swing on the hinges H. O are the chucks ormetal pins moving through the frame A, and which slip out, by means ofthe springs L. into suitable notchesor holes in the braces B, as at eand f, and hold the desk-lid D firmly in its place either when up ordown. E are the seat-braces, which are made to turn on the pivots g inthe frame A so that the seat can-be readily turned up against its backwhen desired. F is the main shelf for holding the books, atlas, slate,&c. G is the pocket or small shelf in front of the shelf F, for holdingpens, pencils, &c.

When it is desired to put down the desk and close it up, the chuck O ispushed in with the finger at c, and with the other hand the desk-lid Dis lowered down and covers up the shelf F and pocket G and hides themfrom View, while the chucks G slip out again through the holes f in thebrace B and fasten the lid down, and prevent it from making a noise; andwhen the seat is turned up it makes a compact folded desk, and allarticles inside of it are safe from exposure or dust. WVhen the desk isdesired to be raised, the chucks O are pushed in at fwith the finger,the desk-lid D raised, and as soon as it reaches its proper position thechucks O slip back to their place through c, and securely hold thedesk-lid D up in its proper position.

What I claim as my invention is The combination, in a school-desk, ofthe frame A, desk-brace B having the slots 6 and f, the chucks G, andsprings L, when combined and arranged with the other parts of the desk,as herein shown.
